A client has been taking a prescribed calcium channel blocker therapy for approximately 2 months. The home care nurse monitoring the effects of therapy should determine that drug tolerance has developed if which is noted in the client?
- A. Decrease in weight
- B. Increased joint pain
- C. Output greater than intake
- D. Gradual rise in blood pressure
Correct Answer: D
Rationale: Drug tolerance can develop in a client taking an antihypertensive such as a calcium channel blocker, which is evident by rising blood pressure levels. The primary health care provider should be notified, who may then increase the medication dosage, change medication, or add a diuretic to the medication regimen. The client is also at risk of developing fluid retention, which would be manifested as dependent edema, intake greater than output, and an increase in weight. Joint pain is not associated with this form of tolerance.

The nurse is caring for a client with a terminal condition who is dying. Which respiratory assessment findings should indicate to the nurse that death is imminent? Select all that apply.
- A. Dyspnea
- B. Cyanosis
- C. Tachypnea
- D. Kussmaul's respiration
- E. Irregular respiratory pattern
- F. Adventitious bubbling lung sounds
Correct Answer: A,B,E,F
Rationale: Respiratory assessment findings that indicate death is imminent include poor gas exchange as evidenced by hypoxia, dyspnea, or cyanosis; altered patterns of respiration, such as slow, labored, irregular, or Cheyne-Stokes pattern (alternating periods of apnea and deep, rapid breathing); increased respiratory secretions and adventitious bubbling lung sounds (death rattle); and irritation of the tracheobronchial airway as evidenced by hiccups, chest pain, fatigue, or exhaustion. Kussmaul's respirations are abnormally deep, very rapid sighing respirations characteristic of diabetic ketoacidosis. Tachypnea is defined as rapid breathing.
During history taking of a client admitted with newly diagnosed Hodgkin's disease, which symptom should the nurse expect the client to report?
- A. Weight gain
- B. Night sweats
- C. Severe lymph node pain
- D. Headache with minor visual changes
Correct Answer: B
Rationale: Assessment of a client with Hodgkin's disease most often reveals night sweats; enlarged, painless lymph nodes; fever; and malaise. Weight loss may be present if metastatic disease occurs. Headache and visual changes may occur if brain metastasis is present.
A client is diagnosed with diabetes insipidus. The nurse should plan interventions to address which manifestations of this disorder? Select all that apply.
- A. Bradycardia
- B. Hypertension
- C. Poor skin turgor
- D. Increased urinary output
- E. Dry mucous membranes
- F. Decreased pulse pressure
Correct Answer: C,D,E,F
Rationale: Diabetes insipidus is a water metabolism problem caused by an antidiuretic hormone (ADH) deficiency (either a decrease in ADH synthesis or an inability of the kidneys to respond to ADH). Clinical manifestations include poor skin turgor, increased urinary output, dry mucous membranes, decreased pulse pressure, tachycardia, hypotension, weak peripheral pulses, and increased thirst.
The nurse is performing an admission assessment on a client admitted with a diagnosis of Raynaud's disease. The nurse assesses for the associated symptoms by performing which actions?
- A. Checking for a rash on the digits
- B. Observing for softening of the nails or nail beds
- C. Palpating for a rapid or irregular peripheral pulse
- D. Palpating for diminished or absent peripheral pulses
Correct Answer: D
Rationale: Raynaud's disease is vasospasm of the arterioles and arteries of the upper and lower extremities. It produces closure of the small arteries in the distal extremities in response to cold, vibration, or external stimuli. Palpation for diminished or absent peripheral pulses checks for interruption of circulation. Skin changes include hair loss, thinning or tightening of the skin, and delayed healing of cuts or injuries. A rash on the digits is not a characteristic of this disorder. The nails grow slowly become brittle or deformed, and heal poorly around the nail beds when infected. Although palpation of peripheral pulses is correct, a rapid or irregular pulse would not be noted.
A client who survived a house fire is experiencing respiratory distress, and an inhalation injury is suspected. What should the nurse monitor to determine the presence of carbon monoxide poisoning?
- A. Pulse oximetry
- B. Urine myoglobin
- C. Sputum carbon levels
- D. Serum carboxyhemoglobin levels
Correct Answer: D
Rationale: Serum carboxyhemoglobin levels are the most direct measure of carbon monoxide poisoning, provide the level of poisoning, and thus determine the appropriate treatment measures. The carbon monoxide molecule has a 200 times greater affinity for binding with hemoglobin than an oxygen molecule, causing decreased availability of oxygen to the cells. Clients are treated with 100% oxygen under pressure (hyperbaric oxygen therapy). Options 1, 2, and 3 would not identify carbon monoxide poisoning.
